Yes, it does benefit the GC to set the properties to null. Doing so removes the references from the element (that is contained in the DOM) to the handler function, and given that it probably is the only reference to the function it makes the function eligible for collection. However, unless the function is a … Read more
If for some bizarre reason you don’t know at run-time if an object has dispose implemented, you can use this dispose-safe function: /// —- IsDisposable ——————————– /// /// <summary> /// returns true if an object is disposable, false if not /// you can optionally dispose of it immediately /// </summary> public static Boolean IsDisposable(Object Item, … Read more
C++ destruction is deterministic, garbage collection is not. In C++ you can guarantee when destructors will be called, in Java there is no such guarantee at all. In fact, your destructors might never be called in Java. 3 solved What is the difference between Java Garbage collection and C++ object destruction? [closed]
At least two, potentially all three of them. Since the local variables are not used after line 11 the JVM is free to set them to null, and they become eligible for garbage collection. From JLS 12.6.1: Optimizing transformations of a program can be designed that reduce the number of objects that are reachable to … Read more
What algorithms are used? Java uses TLAB (Thread Local Allocation Buffers) for “normal” sized objects. This means each thread grab some Eden space and turns this grab of memory into individual objects. Thus small objects are typically sequential in memory for that thread, except if a new chunk of memory needs to be grabbed. Large … Read more
Amit i’ve seen your other question, what matters is always only reachability, it doesn’t matter how you use student, it will always be reachable until the class that contains it is reachable. Update, regarding the question you added: I mean which case (CASE-1/CASE-2) is more GC efficient in terms of Time? Neither because you do … Read more
You should call Dispose(). Even if that doesn’t mean all memory gets freed immediately, all resources opened by the form (timers, files, etc.) should be closed then, if the form is programmed properly. Of course, the form will also be disposed of automatically when the GC runs the next time, but you can make it … Read more
No, the destructor (~myClass) just does the stuff you want him to do when an object is no longer needed, like freeing resources (files, connections, …). Its the opposite of the constructor (myClass), where you set up your object (getting connections, etc). The GC removes all pointers to the myClass-object when it goes out of … Read more
